Pre-winter wheat field management in order to promote the main, nurturing strong seedlings, lay the foundation for wheat safe winter. The main measures are as follows: First, re-seeding and replanting. After the emergence of wheat, seedlings should be checked in time, and the wheat fields lacking seedlings and ridges should be replanted as early as possible, and the phenomenon of lack of seedlings and broken ridges should be eliminated. If the wheat seedlings grow to the 3 to 4 leaf stage, there are still lack of seedlings and broken ridges, you can combine sparse seedlings and seedlings for transplanting to make up the seedlings. The second is cultivating loose soil. In the wheat seedling stage for timely cultivator, with warming, security, weeding, broken knot and other effects. In view of the fact that most of the plots in this year have weak seedlings, many weeds, and heavy build-ups, local governments must use pre-winter plowing as an important technical measure for the management of wheat fields, especially after the emergence of wheat, rain, winter irrigation, or other reasons. Cause the soil compacted land, but also timely scratching, in order to promote root and seedling growth robust. The third is suppression. Repression can crush the clods, seal the cracks, make the soil and the root system close together, is conducive to the root of the water absorption and utilization, reduce water evaporation, maintain a good soil moisture, prevent the wheat seedlings were frozen to death. Therefore, for wheat fields with a large amount of ploughing soil and suspended soil at the time of sowing, it is necessary to suppress the wheat fields before winter to crush the soil blocks to sink the soil and promote the growth of seedlings. In addition, for partially grown wheat fields, repression can be carried out before and after the beginning of winter to suppress the growth of seedlings on the ground and make Miao Miao grow stronger. The fourth is anti-freezing and anti-staining. First, we must cultivate strong seedlings before winter. Second, we must pay attention to the changes in the weather, and timely irrigation before cooling down. Third, timely cover grass insulation. The fifth is due to fertilization. For wheat fields where basal fertility is sufficient and where fertility is better, it is generally not necessary to top-dress fertilizer before winter. However, for wheat fields without basal fertilizer or basal fertilizer insufficiency and poor soil fertility, timely fertilizer should be applied before winter, in addition to benefiting from the transformation of strong wheat seedlings before winter, it also has the effect of winter fertilizer and spring. The amount of topdressing nitrogen fertilizer before winter is generally about 20% of the total fertilizer. With the exception of nitrogen fertilizers, phosphorus-potassium fertilizers should not be applied to winter wheat crops where no phosphorus and potassium fertilizers are used in the base fertilizer. Sixth, weeding and disease prevention. Under the pre-rainy weather conditions, the prevention and control of pests and weeds will be focused on, especially the control of sheath blight and underground pests. Field management of winter wheat after winter should adhere to the promotion and control of integration, sub-regional, sub-type, sub-seedling strengthen water and fertilizer regulation, improve the quality of wheat groups, and lay the foundation for stable production and high yield. The main measures are as follows: First, cultivating in early spring. All types of wheat fields in early spring and return to the green stage should be cultivating loose soil in order to increase the temperature and promote early-onset seedlings. The wheat fields without cracks in the field before winter and cracks in the fields can be repressed in due time to crack the cracks and prevent or reduce the freezing and killing of dead seedlings in early spring. The second is water and fertilizer management. For wheat fields with too small groups (or low-yielding fields), watering and fertilizing should be carried out before returning to the green stage (before and after the spring leaves of the second spring), and the amount of topdressing can be controlled to about 40% of the total amount of topdressing in the spring to promote Growing tillering, strive for panicles. After the jointing stage (before and after the spring leaves from the fifth leaf to the sixth leaf), the second fertilizer and water management will be carried out. The amount of top dressing will be about 60% of the total amount of top dressing in the spring to promote large spikes, multiple grains, and grain weight. For wheat fields with a population of more than 600,000 (or high-yield wheat), watering and fertilizing in spring have to be postponed to control the growth of ineffective tillers. At the late jointing stage (before and after the spring leaves from the fifth spring to the sixth leaves), the amount of fertilizer to be applied in spring can be applied at one time. For wheat fields that are sown too late, the basic seedlings are too large (more than 350,000 per mu) and no tillers are available before winter, watering topdressing can be carried out in the early jointing stage (before and after the fourth leaf of spring spring grows). About 80% of the amount, flowering to the beginning of grain filling and then the remaining fertilizer with water topdressing. The third is prevention and control. During the period of wheat's rise, the wheat fields with lodging risk should be controlled according to the seedlings and varieties, and the plant growth retardant should be sprayed in a timely and appropriate manner, such as "Mai Yefeng", "Paclobutrazole" and "Shuangfeng". An" and so on. The fourth is disease prevention and pest control. In the area south of the Huaihe River, attention was paid to the prevention of strip rust, head blight, and other epidemic diseases. Huanghuaihai wheat area was noted for rust and powdery mildew, and Shaanxi-Gansu-Ningmai District was concerned with rust and wheat seed flies. China Agricultural Network Editor
